This removes black streaks

In an effort to remove the black streaks on my fiberglas coach walls I have tried several different methods, none seem to work very well. Other than a full blown compound buffing and wax, here is what I just discovered.

After scrubbing with a brush using soap and water, and drying, I took a rag dampened lightly with mineral spirits and rubbed gently over the area. The streak vanished. I wiped dry and followed with a cleaner wax and the wall in that spot looks new. Hopefully the picture is clear enough to see the clean spot to the left of the area with black streaks. I did go over the spot you can see with the black streaks with cleaner wax only.

Crown boat hull cleaner and black streak remover is the best product I've used in 47 years of owning a camper.

I use Dry Wash N Guard on ours. The water just beads up and runs off. If some dirt does accumulate, like now after 6 months of winter, it just comes right off with no rubbing.
